Title: Sense amplifier
Inventor: KUSABA SUSUMU
IPC: G11C7/06
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve the operation speed of a sense amplifier. SOLUTION: When a sense amplifier enable-signal EN is 'H', a NMOS 19, 20 are made an on-state, and the sense amplifier is operated. When a data signal Sda is made 'H' and a data signal Sdb is made 'L', a node NA is made 'H', and a node NB is made 'L'. Potentials of each source of NMOS 12, 16 are varied in accordance with each current and each level of the data signals Sda, Sdb independently and respectively. Because of the above, a level of a node ND is made a ground level, and a level of the node NB is made a lower level. Accompanied by this, a level of the node NA is made a higher level. A level of the node NA is outputted from an output terminal OUTa through an inverter constituted with a PMOS 13 and NMOS 14. In the same way, a level of the node NB is outputted from an output terminal OUTb through an inverter constituted with a PMOS 17 and NMOS 18.

Title: Ink supplying method for printing/recording ink carrier
Inventor: AKUTSU HIDEKAZU
IPC: B41M5/382
Filed: 1989-03-15
Abstract: PURPOSE:To adhere thermally fusible ink stably and uniformly by applying voltage between the conductive layer on an ink carrier and an ink supply carrier, thereby transferring charged conductive ink powder from the ink supply carrier onto an ink peeling layer. CONSTITUTION:A used printing/recording ink carrier is fed to a powder ink supply unit 7 for the purpose of regeneration of thermally fusible ink layer. The powder ink supply unit comprises a powder ink carry roll having a conductive sleeve which is applied with bias voltage from a power supply 72. Bias voltage having polarity reverse from that of the voltage being applied onto the sleeve is applied from a power supply 51 onto the conductive layer of the printing/recording ink carrier. Since dielectric thermally fusible ink powder 9 fed through the powder carrying roll is charged, the powder moves electrostatically to an ink transfer track, i.e., a portion where the ink peeling layer is exposed. Then the printing/recording ink carrier is heated and pressurized by means of an ink layer surface arranging unit, thus regenerating the thermally fusible ink layer formed thereon.

The entire device is then simultaneously started and the stirring of the coating compd. is started by a pump 4 for circulating the coating compd. The coating compd. is first passed through an AC magnetic field dispersing device 5 and is then passed through an ultrasonic homogeneizer 6 and a sand mill 7 in this order. The coating compd. is then passed through the filter 8 and is subjected to viscosity checking again by a viscometer 9. This coating compd. is passed through the pump 4 and is sent to a coating nozzle 10. There is a filter 16 in the nozzle 10 and the coating compd. is returned to the tank 3 without being discharged by the OFF of an ON/OFF valve 11. This operation is repeated until the viscosity stabilizes and thereafter, the prescribed viscosity is maintained by the output control of a personal computer 14. After the circulation for >=12hr, the valve 11 is turned ON to discharge coating compd. from the nozzle and to apply the same on an aluminum disk 17.

Title: Specially effective waveform generator
Inventor: YAMAMOTO SHUNICHI
IPC: H04N5/265
Filed: 1985-03-26
Abstract: PURPOSE:To insure a black frame against appearing on an effective screen with respect to the quick operation of a fader by outputting two types of effective waveforms having different delay times to a fader control signal. CONSTITUTION:First, a waveform synthesizing circuit 23 adds or mixes, instead of adding, outputs of horizontal and vertical periodical basic wave generating circuits 21 and 22, and synthesizes a waveform. With the aid of a fader control signal Vf the 1st slice circuit 24 slices the synthesized waveform to obtain a waveform output for a digital specific effect device Vd. The output has no delay with respect to a change in the fader control signal. A delay circuit 26 delays the fader control signal Vf, which slices the 2nd slice circuit 25, thereby obtaining the effective waveform output Va for a specially effective amplifier. Here the delay amount of the delay circuit 26 is set equal to the one until an output video signal can be obtained from the key signal input of the digital special effect device.

Abstract: PURPOSE:To prevent a high original density part from the reduction of image density by setting up a developing bias voltage to be impressed during developing operation so that it is gradually reduced every development in accordance with the reduction of the potential of an electrostatic latent image formed on a photosensitive body. CONSTITUTION:An original platen 5 is moved from the left end side in the right direction, the electrostatic latent images of an original are successively formed on respective photosensitive drums 7c, 7y, 7m and the drums 7c, 7y, 7m complete respective development by three rotations, two rotations and one rotation respectively until the original platen 5 is completely carried up to the right end side. In this case, the absolute value of the developing bias voltage is gradually reduced in the order of the 1st, 2nd and 3rd development to keep the potential difference from that of the electrostatic latent image almost at a constant value. Even if the developing operation is continued up to the 3rd times, a developer temporarily adhering to the surface of the electrostatic latent image can be prevented from being peeled off by the developing bias voltage, so that the reduction of the image density in a high original density part can be suppressed and the image quality can be improved.
